Abstract

A device comprising a metallic conical portion, said conical portion substantially hollow having a vertex end and a base end, a first cylindrical portion disposed annularly about the base end of the conical portion, a metallic second cylindrical portion coupled to the vertex of the conical portion, said cylindrical portion having a threaded aperture, and an antenna feed coupled to the threaded aperture. The device may have a patch disposed on an insulator portion connected to the second cylindrical portion, said patch and insulator portion each having an aperture, and a metallic ground portion connected to the insulator portion, said ground portion having an ground aperture, and a threaded screw disposed through the ground aperture, the patch, the insulator aperture and into the threaded aperture. An RF feed may be created by coupling the threaded aperture to a conductive material disposed on the insulator portion.

Claims

exact text as granted — not AI-modified
1. A device comprising:
 a metallic conical portion, said conical portion substantially hollow having a vertex end and a base end; 
 a first cylindrical portion disposed annularly about the base end of the conical portion; 
 a metallic second cylindrical portion coupled to the vertex of the conical portion; 
 an antenna feed coupled to the second cylindrical portion; 
 a patch connected to the second cylindrical portion, said patch disposed on an insulator portion, said patch and insulator portion each having apertures; 
 a metallic ground portion connected to the insulator portion, said ground portion having an ground aperture, and 
 a threaded screw disposed through the ground aperture, the insulator aperture and the patch aperture and into the second cylindrical portion. 
 
     
     
       2. The device of  claim 1  further wherein the antenna feed is coupled to the second cylindrical portion through the patch. 
     
     
       3. The device of  claim 1  wherein the diameter of the base end is approximately either 5 centimeters or 2.4 centimeters. 
     
     
       4. The device of  claim 1  wherein the second cylindrical portion has an aperture for receiving a fastener. 
     
     
       5. The device of  claim 4  wherein the aperture is threaded and the fastener is a screw. 
     
     
       6. The device of  claim 4  wherein the aperture is not threaded and the fastener is a screw and a nut assembly. 
     
     
       7. A device comprising:
 a metallic ground portion, said ground portion having a plurality of ground apertures; 
 at least one insulator portion disposed on the ground portion; 
 a plurality of patches disposed on the insulator portion; 
 a conical radiator connected to each patch, and 
 a feed connector electrically coupled to each conical radiator. 
 
     
     
       8. The device of  claim 7  wherein the feed connector is a metal adhered to each insulator portion. 
     
     
       9. The device of  claim 7  wherein the radiators are spaced apart a distance of approximately either 8.75 centimeters or 4.2 centimeters. 
     
     
       10. The device of  claim 7  wherein the diameter of the base of the conical radiator is approximately either 5 centimeters or 2.4 centimeters. 
     
     
       11. A radio electrically coupled to the device of  claim 7 . 
     
     
       12. An access point electronically coupled to the device of  claim 7 .
